Ocean Acidification Will not Kill Coral Reefs and Shellfish

When the slight global warming that occurred between 1970 and 2000 came to a virtual standstill, the doomsayers adopted “climate change” which apparently means that all extreme weather events are caused by human emissions of carbon dioxide (CO²). Cold, hot, wet, dry, wind, snow, and large hailstones are attributed to humanity’s profligate use of fossil fuels.

But the pause in global warming kept on and became embarrassing around 2005. Something dire was needed to prop up the climate disruption narrative. “Ocean acidification” was invented to provide yet another apocalyptic scenario, only this one required no warming or severe weather, only more CO² in the atmosphere.

The story goes that as CO² increases in the atmosphere the oceans will absorb more of it and this will cause them to become acidic, well not exactly, but at least to become less basic. This in turn is predicted to dissolve the coral reefs and kill the oysters, clams, mussels, and microscopic algae that have calcareous shells. It was named “global warming’s evil twin”.

Seawater in the open ocean is typically at a pH of 8.0-8.5 on a scale of 0-14 where 0 is most acidic, 14 is most basic and 7 is neutral. Ocean acidification from increased CO² is predicted to make the ocean less basic, perhaps to pH 7.5 under so-called worst-case projections. How do I know that increased CO² will not kill the coral reefs and shellfish? Let me count the ways.

First, contrary to popular belief, at 400 parts per million (0.04%), CO² is lower now in the atmosphere than it has been during most of the 550 million years since modern life forms emerged during the Cambrian period. CO² was about ten times higher then than it is today. Corals and shellfish evolved early and have obviously managed to survive through eras of much higher CO² than present levels. This fact alone should negate the “predictions” of species extinction from CO² levels that are nowhere near the historical maximum.

This alarmist propaganda goes against the real data. Penn State Professor Michael Mann has made similar claims of modern temperatures being the warmest, but such “Hockey Stick” temperature claims have been demolished in the scientific literature.

Opinion by Anthony Cox
I wrote before about the ABC’s bias and the real
cost of the ABC to the Australian community. Since then the Abbott
government has announced reasonable budget cuts but the ABC has sunk further
into its betrayal of its Charter and of the Australian community.
In a recent poll about the farcical China/US deal about
emissions the ABC’s The Drum initially showed this result: 12/11/2014: China and the US have struck a new deal to limit greenhouse gas emissions. Do you think Australia will need to adjust its climate change policies as a result? No 55% Yes 44% Unsure 1%

Given the ABC’s Left/Green readership a remarkable result.
However shortly the result
was changed to this: 12/11/2014: China and the US have struck a new deal to limit greenhouse gas
emissions. Do you think Australia will need to adjust its climate change
policies as a result?Yes 76% No 23% Unsure 1% 6001
